Definitions

  • the invention relates to a device for emptying a tanker filled with flowable petroleum products, wherein the tank car has on the top side a filling and removal opening, a method for emptying the tank car and the use of the device.
  • the present invention seeks to provide a device for emptying a tanker filled with flowable petroleum products available, which makes it possible in a simple manner and without great difficulty to liquefy and dissipate the solidified due to heavy frost petroleum product.
  • WO 95/15287 discloses a device according to the preamble of claim 1.
  • a device according to claim 1 has been found.
  • the corresponding downpipe is inserted into the filling and removal opening located on the top side of the tank wagon, so that its mouth lies in the region of the filling level of the solidified petroleum product contained in the tank wagon.
  • the downpipe is connected with its two delivery pipes to the corresponding pipes, which in turn are connected to the preheating, so that a closed circuit in principle is formed.
  • the same petroleum product is preferably stored, which is also filled in the tank car.
  • the petroleum product is heated to a suitable temperature, for example at 60 ° C or even at 85 ° C.
  • This heated petroleum product is fed from the preheat tank via the feed line and the second pipe into the conveyor pipe and introduced via this into the tank car, so that the heated petroleum product heats up the liquefied petroleum product contained in the tank car and liquefied.
  • the supplied heated petroleum product and the liquefied petroleum product which is located in the tank car, discharged and returned via the first pipe to the preheating.
  • a subset of the liquefied petroleum product, which is withdrawn from the tank car is diverted from the drain line and fed via a feed line in a return line, which is connected to a storage tank in which the volume discharged from the tank car stored and stored.
  • the residual volume, which is not diverted via the delivery line, is reheated in the preheating tank to target temperature and introduced via the supply line, the second pipe and the second delivery pipe back into the tank car.
  • the downpipe With decreasing level within the tank car, the downpipe can be lowered deeper into the tank car or the downpipes of the downpipe can be lowered accordingly to follow the sinking level within the tank car.
  • the inventive design makes it possible to unload tank cars of flowable petroleum products, even if they are frozen in heavy frost in the tank car. For this purpose, no foreign media, so no hot steam or the like required, which could form an additional source of interference during unloading.
  • a feed pump is turned on.
  • the preheating for example, has a volume of 10 m 3 , but the preheating is not completely filled with flowable petroleum product, but preferably only about 80%, so that overfilling of Vortex interchangeers is avoided in any case.

  • the preheating is a thermally insulated vessel, so that heat losses are avoided by heat dissipation to the environment or reduced.
  • an electric heater is installed in the supply line.
  • a switching valve is installed in the delivery line, by means of which the delivery line is to be opened and closed.
  • the delivery line By closing the switching valve, the delivery line can be separated, so that a circulation of the liquefied petroleum product in the circulation is possible. Upon reaching a certain level in the preheating the switching valve is opened so that then in any case, the excess quantity can be discharged via the delivery line in the storage tank.
  • At least some lines have a thermal insulation, in particular an insulating jacket.
  • This measure serves to prevent a freezing of the lines and to avoid unwanted heat loss to the environment or at least to reduce.
  • At least some lines have an electric heater, in particular an electric heating jacket.
  • the heating power is preferably designed such that the delivery of the medium can also take place in the drain line at temperatures greater than 70 ° C.
  • a short-circuit line to be opened or closed by means of a valve is provided between the supply line and the discharge line.
